Sabatier phenomenon in chemoselective gas-sensing reactions induced by Ag cluster coordination.

The Sabatier principle in heterogeneous catalysis provides guidance for designing optimal catalysts with the highest activity. We report a new Sabatier phenomenon induced by nanoclusters on different atomic scales in gas-sensitive reactions. We prepared a series of Ag nanocluster catalysts with coordination structures ranging from Ag to Ag through a surface coordination strategy.

Diagnosis of primary amoebic meningoencephalitis by metagenomic next-generation sequencing: A case report.

Primary amoebic meningoencephalitis (PAM) caused by is a fatal infection with a mortality rate of more than 95%, despite advances in antimicrobial chemotherapy and supportive care. Initial manifestations of PAM are indistinguishable from bacterial meningitis. Prompt diagnosis and antifungal treatment may help decline the overall mortality.

The mechanism of epithelial-mesenchymal transition induced by TGF-β1 in neuroblastoma cells.

Neuroblastoma is the second most common extracranial malignant solid tumor that occurs in childhood, and metastasis is one of the major causes of death in neuroblastoma patients. The epithelial-mesenchymal transition (EMT) is an important mechanism for both the initiation of tumor invasion and subsequent metastasis. Therefore, this study investigated the mechanism by which transforming growth factor (TGF)-β1 induces EMT in human neuroblastoma cells.

Laparoscopic Radical Nephrectomy of Wilms' Tumor and Renal Cancer in Children: Preliminary Experience from a Two-Center Study in China.

Background: To report the preliminary experience of laparoscopic radical nephrectomy (LRN) in children with Wilms' tumor (WT) and renal cancer.

Patients And Methods: From January 2010 to October 2013, the medical records of 7 cases of WT or renal cancer in children treated by LRN at two medical centers in China were reviewed.

Results: All the patients were treated by LRN, and 3 of them underwent preoperative chemotherapy before surgery.

Chemical synthesis and biological activities of 3-alkyl pyridinium polymeric analogues of marine toxins.

Unlabelled: Two new large poly-1,3-dodecylpyridinium salts, APS12 and APS12-2 of 12.5- and 14.7-kDa size, respectively, were synthesised and tested for their pore-forming and transfection capabilities in HEK 293 and undifferentiated mouse ES cells using patch-clamp recording, Ca(2+) imaging and flow cytometry.

Lateral buttock and postanal congenital dermal sinus tract.

We present 2 rare cases of lateral buttock and postanal congenital dermal sinus tract. These 2 children were noted to have a pit in the left upper lateral buttock and a postanal orifice after birth. Magnetic resonance imaging, computed tomography, and ultrasonography showed an inflammatory mass lesion in the buttock and a funicular structure adjacent to the rectum.

Oligomeric rod-disc nematic liquid crystals.

Six new oligomeric nematic liquid crystals are reported consisting of a triphenylene-based core attached to which are six 4-cyanobiphenyl units via flexible alkyl spacers.

Potential diagnostic value of pancreatic isoamylases for pancreaticobiliary maljunction with mild biliary dilatation in patients and a porcine model.

Purpose: The aim of this study was to evaluate the diagnostic value of serum pancreatic isoamylases for pancreaticobiliary maljunction (PBM) with mild biliary dilatation.

Methods: Serum and bile from 8 children with PBM and mild biliary dilatation (6 to 11 mm in diameter) and 4 young pigs with an anastomosis constructed between an isolated pancreas-duodenal segment and the gallbladder were studied for pancreatic isoamylases. Using an electrophoretic technique, the assay of pancreatic isoamylases was expressed by peak appearance rate (PAR).
